Abstract (en)
There is provided a transmission device capable of preventing increase of retransmission information or encoding redundant bit and improving a throughput in a MIMO communication method. In this device, an encoding unit (130) subjects data transmitted from a first transmission antenna (110) and a second transmission antenna (120) each formed by a plurality of antennas, to encoding processing all at once. Modulationunits (113, 123) modulate the data encoded by the encoding unit (130) for each of the first and the second transmission antennas (110, 120). Transmission units (115, 125) process the modulated data so that it can be transmitted from the corresponding first and the second antennas (110, 120). A transmission control unit (160) performs transmission control of the data transmitted from the respective antennas (110, 120). When retransmitting data, the transmission control unit (160) retransmits the data transmitted from a transmission antenna having a smaller number of antennas than the first and the second antennas (110, 120).
